For ease of understanding, some of the matters related to the embodiments of the present application are described below:
1. and the sense of general integration.
Future B5G and 6G wireless communication systems are expected to provide various high-precision sensing services such as indoor positioning of robot navigation, wi-Fi sensing of smart home and radar sensing of automatic driving automobiles. The sensing and communication systems are typically designed separately and occupy different frequency bands. Then, due to the widespread deployment of millimeter wave and large-scale Multiple-Input Multiple-Output (MIMO) technologies, communication signals in future wireless communication systems tend to have high resolution in both the time domain and the angle domain, which makes it possible to realize high-precision sensing with the communication signals. It is therefore desirable to jointly design the sensing and communication systems so that they can share the same frequency band and hardware to improve frequency efficiency and reduce hardware costs. This has prompted research into communication and awareness integration (Integrated Sensing And Communication, ISAC). ISACs will become a key technology in future wireless communication systems to support many important application scenarios. For example, in future networks of autonomous vehicles, the autonomous vehicle will obtain a large amount of information from the network, including ultra-high resolution maps and near real-time information, to navigate and avoid upcoming traffic jams. In the same case, radar sensors in autonomous vehicles should be able to provide powerful, high resolution obstacle detection functions, with resolutions in the order of centimeters. ISAC techniques for autonomous vehicles offer the possibility of high data rate communication and high resolution obstacle detection using the same hardware and spectrum resources. Other applications of ISACs include Wi-Fi based indoor positioning and activity recognition, communication and sensing of unmanned aircraft, XR, radar and communication integration, and the like.
The JSAC obtains the integrated low-cost realization of communication and perception dual functions in a mode of sharing hardware equipment and defining functions by software, and is mainly characterized in that: the structure is unified and simplified, the functions are reconfigurable and expandable, and the efficiency is improved and the cost is reduced. The advantages of communication perception integration mainly have three aspects: firstly, the equipment cost is reduced, the size is reduced, secondly, the spectrum utilization rate is improved, and thirdly, the system performance is improved.
The development of ISACs is divided into four phases: coexistence, co-operation, co-design, and co-collaboration.
Coexistence: communication and perception are two mutually separated systems, the two systems can mutually interfere, and the main method for solving the interference is as follows: distance isolation, frequency band isolation, time division operation, multiple input multiple output (Multiple Input Multiple Output, MIMO) techniques, precoding, and the like.
And (3) common operation: the communication and perception share the hardware platform, the common performance is improved by utilizing the common information, and the power distribution between the communication and perception has a great influence on the system performance.
And (3) co-designing: communication and sensing become a complete joint system, including joint signal design, waveform design, code design, etc., with chirped waveforms, spread spectrum waveforms, etc., in the early stage, and later focused on orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) waveforms, MIMO techniques, etc.
Co-operation: and a plurality of communication perception integrated nodes cooperate with each other to realize a public target. For example, radar detection information is shared through communication data transmission, and typical scenarios are driving assistance systems, radar-assisted communication, and the like.
2. Radar technology.
With the development of radar technology, radar detection targets not only measure the distance of a target, but also measure the speed, azimuth angle and pitch angle of the target, and extract more information about the target from the above information, including the size and shape of the target, and the like.
Radar technology was originally used for military use to detect targets for aircraft, missiles, vehicles, ships, etc. With the development of technology and the evolution of society, radars are increasingly used in civil scenes, and a typical application is that weather radars measure information about the position, strength and the like of cloud and rain by measuring echoes of meteorological targets such as cloud and rain so as to forecast weather. Further, with the vigorous development of electronic information industry, internet of things, communication technology and the like, radar technology starts to enter into daily life application of people, and convenience, safety and the like of work and life are greatly improved. For example, automotive radars provide early warning information for driving of vehicles by measuring distances and relative speeds between vehicles, between vehicles and surrounding objects, between vehicles and pedestrians, etc., greatly improving the safety level of road traffic.
There are many ways of classifying radars in the technical field. The positional relationship between radar transmitting and receiving stations can be divided into: single-station radar and double-station radar, as shown in the following figures. For single-station radars, the signal transmitter and receiver are integral and share an antenna; the method has the advantages that the target echo signal and the local oscillator of the receiver are naturally coherent, and the signal processing is convenient; the method has the defects that signal transceiving cannot be carried out simultaneously, and only signal waveforms with a certain duty ratio can be adopted, so that a detection blind area is brought, and a complex algorithm is required to be adopted for compensation; or the signals are transmitted and received simultaneously, and the transmission and the reception are strictly isolated, but the method is difficult to achieve for high-power military radars. For a double-station radar, the signal transmitter and the receiver are located at different positions; the advantage is that the signal receiving and transmitting can be carried out simultaneously, and the continuous wave waveform can be adopted for detection; the disadvantage is that it is difficult to achieve co-frequency and coherence between the receiver and the transmitter, and the signal processing is complex.
In the application of the general sense integrated wireless sensing, the radar technology can adopt a single-station radar mode or a double-station radar mode.
In a single-station radar mode, receiving and transmitting signals share an antenna, and the received signals and the transmitted signals enter different radio frequency processing links through a circulator; in this mode, continuous wave signal waveforms can be used to achieve non-blind detection, provided that the received signal needs to be well isolated from the transmitted signal, and isolation of about 100dB is generally required to eliminate flooding of the received signal by transmitted signal leakage. Because the receiver of the single-station radar has all information of the transmitted signal, the signal processing can be performed in a matched filtering (pulse compression) mode, and higher signal processing gain is obtained.
In the dual-station radar mode, the isolation problem of receiving and transmitting signals does not exist, and the complexity of hardware is greatly simplified. Since the radar signal processing is based on known information, in the 5G NR feeling integrated application, the radar signal processing can be performed using known information such as a synchronization signal and a reference signal. However, due to the periodicity of the synchronization signal, the reference signal, etc., the blurred image of the signal waveform is no longer a thumbtack, but a thumbtack shape, the degree of delay and doppler blur increases, and the gain of the main lobe is much reduced compared to the single-station radar mode, reducing the range of range and speed measurements. Through proper parameter set design, the measurement range of distance and speed can satisfy the measurement demand of common targets such as automobiles, pedestrians and the like. In addition, the accuracy of measurement of the dual-station radar is related to the position of the transceiver station relative to the target, and an appropriate transceiver station pair needs to be selected to improve the detection performance.
The following describes in detail the perception processing method provided in the embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 2, an embodiment of the present application provides a sensing processing method, as shown in fig. 2, including:
Step 201, a first device obtains a first sensing result and a second sensing result, wherein the first sensing result is a measurement sensing result obtained by sensing a reference target based on a first signal, and the second sensing result is a reference sensing result corresponding to the reference target;
step 202, the first device determines a first parameter according to the first sensing result and the second sensing result, wherein the first parameter is used for representing a measurement error of the sensing measurement;
wherein the reference target comprises an intelligent subsurface device.
In the embodiments of the present application, the above-mentioned intelligent super-surface device may also be referred to as a reconfigurable intelligent surface (Reconfigurable Intelligence Surface, RIS) device. The reference target refers to a target with a known reference sensing result; the reference sensing result (i.e., the second sensing result) is a sensing result obtained by any other method than the first signal, and has high accuracy, so that the reference sensing result can be used to estimate an error in the first sensing result. In order to be able to identify the signal (path or cluster) reflected by the reference object from the received first signal, a first perceived result corresponding to the reference object is obtained. Alternatively, the RIS device described above may have the following characteristics:
1. The method can modulate and load the first incident signal with preset information and then reflect or transmit the first incident signal, so that a path reflected or transmitted by RIS equipment is identified; for example, the RIS device can quadrature cover code (Orthogonal Cover Code, OCC) modulate the incoming signal. Alternatively, the modulation may be amplitude modulation, phase modulation or frequency modulation.
2. The RIS device can control the beam direction and beam forming, so that the first signal can concentrate more signal energy to the direction of the receiving end of the first signal after being reflected or transmitted by the RIS, and the coverage area of the RIS device serving as a reference target is improved.
3. The RIS device is connected to the network, and can perform the above-described configuration of modulation, beam direction, beam forming, signal synchronization, and the like through the network.
Note that the RIS device itself also has errors in timing and frequency; however, if the timing and frequency errors of the RIS device are within the range that the sense of general integration system can tolerate, the timing and frequency errors of the RIS device will not affect the performance of the present application. For example, if the timing error of the RIS device is less than the time length of the Cyclic Prefix (CP) of the OFDM, then the timing error does not affect the performance of the present invention. For another example, if the frequency error of the RIS device is much smaller than the subcarrier spacing of the OFDM signal, then the frequency error will not affect the performance of the present application.
Alternatively, the first device may be a network element with a sensing function, or when at least one of a transmitting end and a receiving end in the sensing measurement process is a base station, the first device may be the base station, or the first device may be a server. The network element of the sensing function can be a network function node in the core network and/or the radio access network (Radio Access Network, RAN) which is responsible for at least one function of sensing request processing, sensing resource scheduling, sensing information interaction, sensing data processing and the like, and can be a base station, or AMF or LMF upgrading in the existing 5G network, or other network functions, or newly defined network function nodes.

The first sensing result may be a sensing result obtained based on the path where the reference target is located, or may be a sensing result obtained based on all paths in the cluster where the reference target is located.
Further, when the reference target includes a plurality of RIS, it is possible to distinguish each RIS device according to modulation information (e.g., a RIS device ID sequence) of each RIS, and determine a measurement error of the perception measurement based on the RIS device having the best signal quality, thereby improving accuracy of error determination. Wherein the signal quality may be determined based on at least one of: reference signal received power (Reference Signal Received Power, RSRP), received signal strength indication (Received Signal Strength Indication, RSSI), signal-to-noise ratio (Signal Noise Ratio, SNR), signal-to-interference-plus-noise ratio (SINR), and the like.
Optionally, the second sensing result may include at least one of: delay, doppler, and angle.
In the embodiment of the application, the first parameter can be determined by acquiring the first sensing result obtained by sensing the reference target based on the first signal and based on the first sensing result and the second sensing result of the reference target, so as to obtain the measurement error of the sensing measurement. In this way, subsequent perceptual measurements may be compensated based on the measurement error. Therefore, the embodiment of the application can improve the accuracy of the perception measurement.

In order to compensate for timing deviation or frequency deviation between the terminal and the base station or phase deviation between the antenna ports of the base station, so that first signal delay or Doppler caused by the perception object or angle of the perception object relative to the base station can be obtained more accurately, a reference target (RIS device) in a known state is perceived through a perception reference signal (first signal): the real time delay of the perceived reference signal from the terminal to the reference target and then to the base station and the angle of the reference target (RIS equipment) relative to the base station can be obtained through the position relation among the terminal, the base station and the reference target (RIS equipment), and the reference target (RIS equipment) is in a static state and the Doppler of the reference target (RIS equipment) is zero; thereby obtaining a second perception result.
